Engineering Material Magic

This completes the technical conversion to a full 2D protocol for electronics generally. Again speed and power will leap ahead and soon we will have it all and it will be cool as well.

With the third dimension getting out of the way we could also be close to effective stacking of technical layers allowing even more space saving.

All good.

Utah engineers discover groundbreaking semiconducting material that could lead to much faster electronics

UNIVERSITY OF UTAH

University of Utah engineers have discovered a new kind of 2D semiconducting material for electronics that opens the door for much speedier computers and smartphones that also consume a lot less power.

The semiconductor, made of the elements tin and oxygen, or tin monoxide (SnO), is a layer of 2D material only one atom thick, allowing electrical charges to move through it much faster than conventional 3D materials such as silicon. This material could be used in transistors, the lifeblood of all electronic devices such as computer processors and graphics processors in desktop computers and mobile devices. The material was discovered by a team led by University of Utah materials science and engineering associate professor Ashutosh Tiwari. A paper describing the research was published online Monday, Feb. 15, 2016 in the journal, Advanced Electronic Materials. The paper, which also will be the cover story on the printed version of the journal, was co-authored by University of Utah materials science and engineering doctoral students K. J. Saji and Kun Tian, and Michael Snure of the Wright-Patterson Air Force Research Lab near Dayton, Ohio.

Transistors and other components used in electronic devices are currently made of 3D materials such as silicon and consist of multiple layers on a glass substrate. But the downside to 3D materials is that electrons bounce around inside the layers in all directions.

The benefit of 2D materials, which is an exciting new research field that has opened up only about five years ago, is that the material is made of one layer the thickness of just one or two atoms. Consequently, the electrons "can only move in one layer so it's much faster," says Tiwari.

While researchers in this field have recently discovered new types of 2D material such as graphene, molybdenun disulfide and borophene, they have been materials that only allow the movement of N-type, or negative, electrons. In order to create an electronic device, however, you need semiconductor material that allows the movement of both negative electrons and positive charges known as "holes." The tin monoxide material discovered by Tiwari and his team is the first stable P-type 2D semiconductor material ever in existence.

"Now we have everything -- we have P-type 2D semiconductors and N-type 2D semiconductors," he says. "Now things will move forward much more quickly."

Now that Tiwari and his team have discovered this new 2D material, it can lead to the manufacturing of transistors that are even smaller and faster than those in use today. A computer processor is comprised of billions of transistors, and the more transistors packed into a single chip, the more powerful the processor can become.

Transistors made with Tiwari's semiconducting material could lead to computers and smartphones that are more than 100 times faster than regular devices. And because the electrons move through one layer instead of bouncing around in a 3D material, there will be less friction, meaning the processors will not get as hot as normal computer chips. They also will require much less power to run, a boon for mobile electronics that have to run on battery power. Tiwari says this could be especially important for medical devices such as electronic implants that will run longer on a single battery charge.

"The field is very hot right now, and people are very interested in it," Tiwari says. "So in two or three years we should see at least some prototype device."

About Me

18 years old, having cleaned out my HS library, I concluded the only ambition worth having was becoming a great genius. An inner voice cheered. Yet it is my path I have shared much to the Human Gesalt. Mar 2017 - 4.56 Mil Pg Views, March 2013 - Posted my paper introducing CLOUD COSMOLOGY & NEUTRAL NEUTRINO described as the SPACE TIME PENDULUM. Sep 2010 -My essay titled A NEW METRIC WITH APPLICATIONS TO PHYSICS AND SOLVING CERTAIN HIGHER ORDERED DIFFERENTIAL EQUATIONS has been published in Physics Essays(AIP) June 2010 quarterly. 40 years ago I took an honors degree in applied mathematics from the University of Waterloo. My interest was Relativity and my last year there saw me complete a 900 level course under Hanno Rund on his work in Relativity. I continued researching new ideas and knowledge since that time and I have prepared a book for publication titled Paradigms Shift. I maintain my blog as a day book and research tool to retain data, record impressions, interpretations and to introduce new insights to readers.
